RELEASING MECHANISM.

To all 'wkomit mag/wncern;

Be it known that I, SAMUEL SEOKENDORI;

a citizen. of the United States, residing at New. York, in the countyand State of New York, have invented certain new and useful Improvementsin Releasing Mechanism, of which the following. is a full, clear, andexactdescription.

The invention which constitutes the sub-. 1

ject: matter of thisapplication relates-to a lorgnette or eye-glass,theconstruction, objects, operation;;and advantages of which will appearfrom the detailed description '1" Fig. 2' isv arear view illustratingthe device. in completely closed position suspended from its cord 01chain. r

Fig. 3 is a longitudinal section taken pentrally through Fig. 2 butlooking in a direc- .tion at right angles to the view in Fig. 2.

Fig. 4 is an enlarged 'detailillustrating the novel-means formaintaining or holding the lorgnette in folded position. 7 V Fig. 5 is adetailview illustrating the re.

- silient connection-between the two bridge portions connecting theglass settings or frames.

Referring. to the drawings in detail the reference numeral-'10designates a sheath or mounting preferably of rectangular construction,provided with an outer fiangeor gallery 11 and a stem 'orneck portion12,

the end of'which is connectedto a cord or f chain 13 from which thelorgnette is nor-.

mally suspended. The mounting is adapted to receive the frames 14 and 15.of the glasses.

These frames are. providedwith bridge por-.v

tions 16 and 17,respectively, pivoted to each other at 18. The frame 14is pivotedat 19 to the mounting 10.

In folding the lorgnette the frame 15, as viewed from Fig. 1, is rotatedin a folding direction about itspivotal point 18 as a center until itcomes into contact with and lies flat upon frame14. The two frames orset tings are now moved or folded bodily in a direction about the pivot19 as a center until they lie flat upon the bottom of the mounting 10,in which condition the frames 14 Specification 'of Letters Patent.

not only enables the setting or frame 15 to v Patented Mar. 11, 1919.Application filed May 10, 1917. Serial No. 167,672. r

. and 1 5 willbe within the borders ofthef be positionedbetween thesetting 14 and the sheath 11, but also enables the successive foldingmovements to take place in planes.

extending in the same: general directions.

The chain l3'is connected to the stem or neck 12 through the ring 21,spring pressed plunger 22 and casing, 23, in which said plunger islocated, said casing being rigidly mounted in saidnecki 12; The plunger22 is provided with a shouldered portion, 'or piston'24 adjacent tolower end which snugly fits the cylindrical casing 23 and in which ithas a limited reciprocating movement. To the shouldered portion 24ispreferably attached a plurality of fins 25 adapted to slide in slots26 in the casing 23. These fins and slots not only serve to limit theupward movement of the plunger 22, but also pre:

vent any rotary movement being imparted thereto. The plunger head 27, towhich the ring 21 is attached, limits the downward movement of theplunger 22. The plunger also carries-a 'member 28 which in thefoldingoperation snaps into a notch 29 contamed in the end of the bridgeportion 16,

,thelatter being rounded .or cam-edged in order to cam the plunger 22outwardly against the tension of a spring 30, located gbetwee'nthe upperend of thecasing 23 and the shoulder 24.

So. long as the me1nber28 is in effective engagement with the notch 29the lorgnette is securely heldinfolded position. If now it is desired touse the lorgnette a pull is exertedupon the chain 13 which retrieves theplunger 22, disengaging the member 28 from the notch .29 when 'theframes will spring out to their correct optical positions about theirrespective pivots as previously described. The frame 15, in foldedposition, locates itself between the frame 14 and the bottom of thesheath 10. When the member .28 is therefore disengaged from notch 29 thespring 31 surrounding the pivot pin 32 1 is strong enough to initiatethe movement of the frames 14' and 15 to open position. From'theforegoing it will be seen that in the operation of folding the lorgnetteor other spectacle the bridge portion is auto matically engaged by thespring-pressed plunger which looks the same in folded position and thatwhen it is desired to use the lorgnette it is only necessary to exert aslight pull upon the chain 13. This chain is inva-' riably anchored andto use the lorgnette it is only necessary to grasp the sheath 1 andexert a slight pull thereon which disengages themember 28 from the notch29 and the parts then open automatically under the tension of the spring31. For all practicalpur- It will of course be understood that the i Vbridgeportions 16 and 17 are provided with" able upon each other andprovided with a poses'therefore the device may be manipu l'atedto openposition by one hand. 1

cooperating shoulders which limitthe opening movement of the same,such'as that employed in connection with an ordinary hinge; it will alsobe understood that the frames 14 and 15, bridge portions 16 and 17mounting 10 and shank 12'may be made of any desired material, and itwill bef-ur-f ther understood that many changes may be made'inp'oint ofdetail and other embodilnents resorted to without necessarily deviatingfrom the true spirit andscope of my 7 plunger for automaticallyinterlocking said sheath and settings in folded relation.
